About Mousse Partners
Mousse Partners is the single family office of Alain and Gérard Wertheimer, the sole owners of the French luxury house Chanel. Operating from New York, it is the proprietary investment division of Mousse Investments Limited (formerly Litor Limited), a Cayman Islands holding company that ultimately controls Chanel. It diversifies the family's Chanel-derived wealth into a globally diversified portfolio spanning private equity, venture capital, real estate, credit, and public markets, prioritizing long-term direct co-investments. It is not a registered investment adviser and does not accept third-party clients.
Founded in 1991 by Charles Heilbronn, a Chanel executive and half-brother of the Wertheimers, Mousse Partners has become increasingly active in direct and co-investment deals across healthcare, finance, consumer brands, and biotech, alongside longer-running venture positions. The structure is tightly bound to Chanel's own corporate holding architecture.
